Think i've figured it out
I started using mb 2 months ago after another friend swore by it (she has just had baby #2). I started testing in the mornings but thought i was doing something wrong - I could only ever see blobs - so started testing in the afternoons and was constantly getting the fern pattern :wall: Started to think I was the most fertile woman on the planet!! This month started doing it first thing in the morning again and got the clear full ferning right on the day I thought I should have been oing. I found that waiting 10 minutes after it dries works best, not 10 minutes from when I smeared - so in total probalby 20 minutes. 2 days to AF, :crossfingers:
